OS&Y Damal Valve

Yirlaade jolngo junngo ina diwa ƴiyal ɓuuɓngal ngal dow walla les, ina diwa damal ngal ngam udditaade walla uddude ɓuuɓol ngol.

Valve damal NRS

Valve damal Non-Rising Stem (NRS), anndiraa kadi valve damal stem yirlotooɗo walla valve damal wedge stem mo ummotaako, ina waɗi nut stem gonɗo e disko oo. Yirlaade jolngo junngo ina wirna ƴiyal valve, ngal ummotoo walla ngal jippina disko oo. Ko ɓuri heewde, jolngo trapezoidal ina masiŋaa e les ŋorol ŋorol ngol. Ndeeɗoo jolnde, jokkondirnde e laawol njiylawu e dow disko hee, waylata dille yirlaade ɗee e dille lineere, ɗum noon wayla torkooru gollordu nduu e doole doolnuɗe.

Njiylawu NRS e OS&Y Gate Valves e nder kuutoragol:

1. Yiyngo Ɓoggol : Ɓoggol valve damal OS&Y ina feeñi e yaasi, ina yiyee, kono ngol valve damal NRS ina udditii e nder ɓanndu valve ngol, yiyataa.
2. Mekanisme gollal : Valve damal OS&Y ina gollira e jokkondire gonɗe hakkunde ƴulɓe e ƴulɓe junngo, ko ɗum ƴettata walla jippinta ƴulɓe e mooɓondiral diski. E nder valve NRS, jolngo junngo ngoo ina wirna ƴiye ɗee, ɗe njirlotoo ko e nderdisko, e ɓoggi mum ina njokkondiri e nut e dow disko ngam nawde ɗum dow walla les.
3. Kollitgol darnde : Ɓoggi diwooje valve damal NRS ko nder. E nder golle, ƴiiƴam ɗam ina yirloo tan, ɗum noon ko yiytere tabitinde ngonka valve oo waawataa. Ko wayno noon, ɓoggi valve damal OS&Y ko yaajɗi, ina addana nokku disko oo yiyeede no laaɓiri e no feewi.
4. Haajuuji nokku : Valveeji dame NRS ina njogii diisnondiral ɓurngal yaajde e tooweeki duumiindi, ina ɗaɓɓi nokku ɗo jolnirtee seeɗa. Valveeji damal OS&Y ina njogii tooweeki ɓurki mawnude so udditaama haa timmi, ina ɗaɓɓi nokku ɓurɗo tiiɗde.
5. Toppitagol & Kuutoragol : Ɓoggol yaajngol valve damal OS&Y ina newna toppitagol e loowdi ɓurndi hoybude. Fiilde nder valve damal NRS ɓuri saɗtude golloraade, kadi ɓuri waawde ustaade e nder direct media erosion, ko ɗum waɗi valve oo ɓuri waawde bonnude. Ko ɗum waɗi, valveeji dame OS&Y ina njogii kuutoragol ɓurngol yaajde.

Desinuuji njuɓɓudi valve damal OS&Y e valve damal NRS ina limtee nii :

1. Valve damal OS&Y:Nut stem valve ina woni e dow ɓuuɓri valve walla e dow ɓuuɓri. So a udditii walla a udditii diski valve, ƴeftude walla jippinde ƴiye valve ɗee ko e yirlaade ƴiye valve ɗee. Ndeeɗoo mbaydi ina nafta e loowde ƴiiƴam valve, ina addana udditgol e udditgol ngol yiyeede no feewi, ko ɗum waɗi ngol huutoreede no feewi.
2. Valve damal NRS:Nut stem valve ina woni e nder ɓanndu valve, ina jokkondiri no feewi e medium. So a udditii walla a udditii diski valve, ƴiiƴam valve ina yirloo ngam heɓde ɗum. Nafoore ngool mbaydi ko tooweeki kuuɓtodinki valve damal ngal ina heddii ko waylaaki, ɗum noon ina ɗaɓɓi nokku ɗo liggortoo ɗoo, ɗum noon ina moƴƴi e valveeji mawɗi walla valveeji ɗi nokku liggortooɗo oo famɗi. Ooɗoo sifaa valve ina foti jogaade kolliroowo udditirɗo/udditiiɗo ngam hollirde nokku ɗo valve oo woni ɗoo. Nafoore ngool mbaydi ko wonde jolɗe ƴiye valve ɗee mbaawaa loowde, ina njuutee e weeyo ngo, ina addana ɗe waawde bonnude.
